Title: Manufacture of aromatic sulphocarboxylic acid-amides and imides
IPC: C07D209/48
Filed: 1936-04-15
Abstract: Carboxylic acid amides and imides are manufactured by reacting a sulphonic acid or sulphonic acid salt of o-phthalic anhydride or of an o-phthalic acid halide or ester, or a substitution product thereof, e.g. the anhydrides, halides or esters of o-phthalic acid mono- or disulphonic acids or of 5-sulpho-4-chlorophthalic acid, with a primary or secondary nitrogenous base containing more than two carbon atoms in the molecule, or a derivative thereof, if desired in the presence of a solvent, e.g. pyridine, quinoline or dimethyl-p-toluidine.  When the carboxylic acid chloride is used it may be produced during the reaction, e.g. with the aid of phosphorus trichloride.  Suitable bases are primary and secondary saturated or unsaturated aliphatic, cycloaliphatic, aromatic, aliphatic-aromatic or heterocyclic amines or their derivatives containing at least one free hydrogen atom attached to the nitrogen, e.g. propyl-, butyl-, amyl-, octyl-, decyl-, dodecyl-, hexadecyl-, octadecyl- and cetylmethyl-amines, aminoethyldimethylamine, monostearylethylenediamine, diethanolamine, lauric acid ethanolamine ester, cyclohexylamine, hexahydrotoluidine, aniline, p-aminophenol, p-chloraniline, benzidine, benzylamine, piperidine, and lauric and stearic acid p-aminoanilides.  The products may be used, alone or in conjunction with other substances, e.g. solvents, salts of mono- or polyvalent metals, soaps or soap-like substances or protective colloids, as textile assistants, e.g. for wetting, cleaning, washing, dispersing and equalizing, for softening the fibre and for increasing the wetting capacity of mercerizing liquors.  In examples: (1) 4-sulphophthalic anhydride is heated with methylcetylamine in pyridine; a solution of the product may be used for washing yolk from wool; (2) 4-sulphophthalic anhydride is heated with amylamine; the product may be added to a solution of sodium hydroxide for mercerizing dried crude yarn; (3) 4-sulphophthalic anhydride is heated with lauric acid p-aminoanilide in pyridine; the product may be used as in (1); (4) stearic acid p-aminoanilide is similarly reacted; the product may be used for softening artificial silk.  A sample has been furnished under Sect. 2 (5) of the product obtained by heating 3 : 5-disulphophthalic anhydride with methylcetylamine in pyridine.  Methylcetylamine is obtainable by heating cetyl chloride with an alcoholic solution of methylamine in a closed vessel at 150--160 DEG  C.

Turning.-Relates to improvements in the toolcarrying turret described and claimed in the parent Specification. Each tool b<1> - - b<8> is mounted in a slotted sleeve n, Fig. 6, the above of which is eccentric to the outer surface to allow of accurate adjustment of the tool. and is carried by a disk a' - - a<8> mounted in a spindle f the tools being approximately in the same plane in the starting position. The dish a<1> is keyed on the spindle and has a pin r on one side engaging a slot s in the disk a<2> which has a similar pin in a slot in the disk a<3> and so on throughout the series. The tools are adjusted by screws t, Fig. 4, and by rotating the sleeves n and are then secured by screws c. This method of carrying the tools enables two or more to be in action at the same time. The tools are held in action by a bar i and when the tool b<1> moves off the end of the bar. a spring or weight rotates the spindle and throws the tool b<1> downwards. Similarlv when the tool leaves the bar, the pin r in the disk a<1> rotates the disk a<2> to throw the tool b<2> downwards and so on. When all the tools have been in use, a stop v on the disk a<8> co-acts with an arm w to prevent further rotation of the spindle which, with the disks, is returned to the starting position by a lever m. In a modification, the spindle is stationary and has a key which in the initial position engages all the disks. As each tool moves off the bar i its disk moves beyond the end of the key and a spring between the spindle and the disit a<1> moves the tools out of action. The tools a.re shown as screw-cutting tools, but other tools may be mounted in a similar way.

Abstract: Mixtures for condensation to thermosetting resins comprise aniline, an aldehyde and anacardic materials, viz. cashew nutshell liquid or distillates, distillation residues, or hydrogenation products thereof, e.g. as described in U.S.A.  Specifications 2,058,456, 2,067,919, 2,181,189 and 2,128,247; polymerized cashew nutshell liquid, as described in U.S.A. Specifications 2,176,059, 2,240,038, 2,292,611, 2,317,585 and 2,338,230, may be employed. Any two reactants may be reacted together and the product with the third. The fusible thermo-setting resin may be used for coating and impregnating paper, cloth, metal and wood, e.g. for making brake linings and clutch facings; the final infusible resins in finely divided form may be used as friction material in such friction elements comprising asbestos and like fibrous material and a binder, e.g. a phenol aldehyde resin.  The addition of the aniline-aldehyde resin even in small amounts up to 1 per cent reduces the tendency to spontaneous combustion of the comminuted cashew nutshell liquid resins.  Up to 33 per cent may, however, be added.  In examples (1), (2) and (3), the reactants are finally cured at 260-275 DEG  F., to give an infusible resin which is ground; an intermediate ground resin may be admixed with asbestos with or without another binder such as a second phenolic resin; (5), (6) and (7), coating compositions are described with xylol, tetrahydrofurfuryl alcohol and petroleum spirits as solvents, to the last of which an alkaline material such as hexamethylene tetramine may be added to improve the curing.
